To all whom it may concern.-

Be it known that I, GEORGE HENRY TAY 5 county of Lancaster, England, have invented new and useful Improvements in Furnaces, (for which I have obtained patents in France, dated March 26, 1889, No; 198,216; in Ger many, dated April 5, 1889, No. 49,337 in Switzerland, dated April 3, 1889, No. 805; in Bel gium, dated April 5, 1889, No. 85,696; in Spain, dated April 24, 1889, No. 9,509; in Italy,

dated May 18, 1889, No. 25,462/9, and in Canada, dated May 20, 1889, No. 32,57 9,) of which the following is a specification.

My invention relates to improvements in that type of furnaces wherein the fuel is converted from the solid into the gaseous form in the central part of the fire-box, and the 20 combustion-chamber is formed between the producer and the outer casing of the fire-box, said apparatus being employed for the generation of steam and other heating purposes.

My invention comprises several modifica- 5 tions. The gas-producer may be of various 7 forms, as hereinafter set forth, as also may the steam-generator, and these may be combined together, those forms being chosen which are most convenient under the particular circum- 3 stances of the case.

The improvements will be hereinafter described in detail, and specifically set forth in the c1aims,-reference being made to the accompanying drawings, in which- Figure 1 is a vertical sectional view of the furnace and boiler, taken on the line A B, Fig. 2. Fig. 2 is a transverse sectional view taken on the line O C, Fig. 1. Fig. 3 is a similar view taken on the line D D, Fig. 1. 40 Fig. 4 is a similar view taken on the line E E, Fig. 1. Fig. 5 is a similar view taken on the line-F F, Fig. 1. Fig. 6 is a vertical sectional View showing a modification of the furnace structure and boiler. Fig. 7 is a vertical sectional view showing another modification of the furnace 'structure. Fig. 8 is a transverse sectional view of the construction shown in Fig. 7. Fig. 9 is averticalsectional view showin g another modification of the furnace structure, and Fig. 10 is a transverse sectional view of the construction shown in Fig. 9.

The invention relates, among other things, to the construction of the brick-work comprising the furnace structure below the central gas-producer A with openings or pas- 5 5 sages for the admission of air, which is required to be mixed with the gas proceeding from the inlets situated at the bottom of the gas-conduits for the purpose of promoting combustion.

Now according to this improvement I form an air chamber or passage 0, Fig. 1, by preference annular, in the brick-work of the furnace structure and adjacent to the firegrate, as shown, for the purpose of conveying the necessary air into the combustion-chamber P to insure perfect combustion of the gases, and such chamber or passage maybe provided with suitable blowers (steam or air) for the purpose of injecting such air. I fur- 7o ther form openings at in the top of this annular chamber 0, and I arrange them concentrically with the combustion-chamber at convenient distances in order to supply such combustion-chamber with heated air for the pur- 7 5 pose of igniting the gases and supporting combustion in as thorough a manner as possible.

To effect a thorough intermixture or admixture of the ascending jets of gas and air proceeding, respectively, from duct-s 6, formed in the brick-work of the furnace or gas-producer, and from the annular chamber 0, before mentioned, I divide these jets into thin streams or streamlets. For this purpose I provide radial sections of fire bricks or blocks a, Fig. 3, and I arrange the same in and around the space between the gas-producer A and the outer brickwork of the furnace structure for about half-way down, whereby the desired object is attained.

In the modification shown in Fig. 6 the gases are led off by a central uptake or flue R from the producer portion A of the furnace through the steam-generator, from the upper part of which they are conveyed by means of an air-tight jointed cross-tube S and diving-fines S S, passing outside the generator and. producer to the combustionchamber P. The furnace in this case is in a measure rendered detachable from the generator, inasmuch as the neck of the furnace fits to the lower part of the uptake or central tube, and the joint between the same is covered and protected by a ring t, of suitable refractory material, thus enabling the boiler to be readily removed for any purpose required. In this arrangement I form around the gasproducer A a Water-jacket or feed-water heater T, suitably stayed, which is supplied with water pumped or otherwise conveyed under pressure from a tank by a pipe V. From this jacket the hot water is discharged by other pipes V into the boiler. After the gases have reached the combustion-chamber they ascend through the tubes of the boiler, having met and mixed with the heated air introducedthrough the opening a from the annular fiue c, or through ducts constructed in the outer brick wall of the furnace structure of the combustion-chamber, (see Figs. 7 and 8,) hereinafter fully referred to, and which admission of air through these ducts is regulated by means of suitable air-grids, thereby heating the air in its passage downward to the re- .quired temperature to promote combustion. The air supplied to the gases for combustion may likewise be heated preparatory to use by.

the waste heat of the products of combustion by any suitable arrangement of air-conduits, so as to economize heat.

Figs. "7 and 8, which are respectively a vertical section and horizontal section, refer to a somewhat modified arrangement of the gasproducer shown Figs. 1, 2, 3, and 6. In this modification the gases collected within the gas-producer A are conveyed therefrom by ducts b constructed in the refractory brick- .Work constituting the walls of the producer. Thence the gases pass underneath and upward through suitable passages or culverts 1) into the combustion-chamber P, where they meet with the heated air from the passages 17 constructed in the brick-work of the furnace structure, and which is admitted and regulated through air-grids 19 It will be obvious that by the arrangement described above the gases and air both become highly heated in their, passage through the respective ducts in the refractory material, and an excellent system of combustion is obtained, which is capable of easy regulatypes 10, respectively, and consists of two producers A A placed within one general annular combustion-chamber. Said producers each have separate charging and clinkering doors, fire-grates, and ash-pits, and are divided or separated bya double oblong partywall extending across the area of the inner furnace and forming a gas-duct or downtake I), through which the gases pass on their way downward, and thence along the passage b and upward through the ducts 1) into the general combustion-chamber P to meet the necessary heated air passing through the passages b 6 into the brick-work of the coinbustion-chamber, as hereinbefore described with reference to Figs. 7 and 8. g

In Fig. 1 I exhibit a steam-generator, which is constructedto especiallyadapt it for use with my improved furnace structure. This generator, as shown, is provided with a set of tubes 2', connected vertically with a fiat cylindricalshaped drum or waste-heat box lo, to which is attached a cylindrical metallic hood g, enveloping the set of tubes t This hood, where bolted to the waste-heat box is, which is below the water-level, is constructed with a flat rim at the top sufficiently wide to admit of a number of relief-tubes h. To the box are fixed another set of tubes j, and these extend from the upper plate of the said box through the lower plate, their free ends coming down into the boiler, but not extending to the lower upward through the fire-tubes 2' into the wasteheat box, causing a suitable and sufficient agitation of the water above the tube-plate, which tube-plate is thus subjected to the frictional action of the water and steam, chiefly owing to the latter rushing to the mouths of the water-tubes, while the contrary action of the two sets of tubes prevents anysediment forming on the lower tube-plate and foaming or priming taking place in the boiler. The object of this arrangement is to keep the tubeplates free from scaly or saline deposit and to allow of their being readily cleaned.

The herein-described improvements considerably enhance the practical utility of this system of selfcontained steam-generator, while the herein-described forms of gas-producer and combustion-chamber can, with obvious modifications, be easily renderedadaptable to existing steam-generators of various such, for instance, as horizontal boilers constructed in self-contained horizontal form.

The herein described forms of steam-gem erator may be readily combined with either of the modified constructions of gas-producer above set forth.

I do not herein broadly claim the steamgenerator constructed as described with reference to Figs. 1, 4, and 5, as such per se c011- stitntes the subject-matter of a separate application for Letters Patent filed February 25, 1890, No. 341,779.
